In 2015 the Interdisciplinary Centre for Mathematical and ComputationalModelling (ICM), University of Warsaw built a modern datacenter and installedthree substantial HPC systems as part of a 168 M PLN (36 M Euro) OCEAN project.Some of the systems were ill-conceived, badly architected and for the fiveyears of their life span have brought minimal ROI. This paper reports on atwo-year intensive effort to reengineer two of these HPC systems into a hybrid,multi-cloud solution called A-CHOICeM (Akademicka CHmura Obliczeniowa ICM). Theintention was to expand the user base of ICM typical HPC system from around 200to 500 to about 100,000 potential general academic users from all institutes ofhigher learning in the Warsaw area. The main characteristics of this solutionare integration of on-premises ICM Cloud with several public cloud providers,building solution tailored to particular groups of academic users,containerization, integration of special computational paradigms like AI andQuantum Computing. Full process of designing the solution, competitive dialoguewith suppliers, and full final specifications for the solution are presented.Several roadblocks, pitfalls and difficulties encountered along the way,including the conservative attitude of "the old school" HPC admins, Universitybureaucracy, national funding policies and others are presented.
